Stormquakes offshore North America and seismic stations from 2006 to 2015. The located stormquakes are shown as the red circles, and the seismic stations are shown as triangles. Due to the location uncertainties, some of the apparent stormquake locations are beyond the coastlines. The yellow contours show regions where stormquakes were detected. The orange contour shows a comparison region offshore Mexico that has been struck by hurricanes but without excitation of stormquakes. The insert shows earthquakes (blue dots) reported in the International Seismological Centre catalog with magnitudes greater than 3 and shallower than 40 km from 2006 to 2015.
